CALL: WEIGHTING_FIELD
WEIGHTING_FIELD uses the internal coordinate system. If you
describe your cell in Cartesian coordinates, then the internal
frame is simply the Cartesian coordinate system. If you use
polar coordinates however, then you should supply the following
parameters:
for x: log(r)
for y: phi, in radians
for z: assumed to be 0
The field is returned in internal coordinates. The internal
coordinates system is Cartesian when the cell is described in
Cartesian coordinates, but when you describe the cell in polar
coordinates, you've to apply the following mapping:
Er = Ex/r
Ephi = Ey/r
Ez = Ez
Here you have to enter the sense wire group number of the
electrodes on which you wish to measure the current. This
number can be obtained by typing SELECT without arguments.
This argument is compulsory.
In periodic cells, the x and y copies of the basic cell
register different currents than the basic cell.
By default, you get the field from the basic copy of the
cell. If you wish to see the field from another copy,
then you have to specify the x and/or y copy number as
appropriate.
